摘要 电力设施作为重要的民生设施,对其工作电流的实时监测具有重要的意义。基于无线传感网络技术,研究开发了由多个电流采集节点以及一个集合无线通信技术的主控模块组成的无线传感网络,实现对配电网电流的监测。其中电流采集节点利用电流互感器采集节点处的电流信号,并通过ZigBee技术将采集结果发送到中央处理单元的协调器单元,经中央处理单元对数据进行处理后采用GPRS技术将数据发送至配网主站服务器,同时采用GSM方式将数据发送给移动终端,比如配网相关工作人员的手机。设计开发了相应模块的硬件电路以及软件程序,测试结果表明,研发的电流监测系统最小可测电流为200mA,动态范围达24dB。 As an important living facility,electric power facility is of great significance to the real-time monitoring of its working current.Based on wireless sensor network technology,a wireless sensor network consisting of multiple current acquisition nodes and a master control module of integrated wireless communication technology is developed to monitor the current of distribution network.The current acquisition node using current transformer current signal acquisition node,and through the ZigBee technology will collect the results sent to the central processing unit coordinator of the unit,by the central processing unit to deal with the data after using GPRS technology sends the data to match the webmaster station server,at the same time using GSM sends the data to mobile terminals,such as mobile phone distribution network related staff.This paper designs and develops the hardware circuit and software program of the corresponding module.The test results show that the minimum measured current of the developed current monitoring system is 200 mA and the dynamic range is up to 24 dB.
